Turner’s backyard deck cost $38.31 per square meter to build. The deck is 9 meters wide and 11 meters long. How much did it cost to build the deck?
Answers
Answer:
$3792.69
Step-by-step explanation:
First, we would find the area,
Area = width x length
Area = 9 x 11
Area = 99\(m^{2}\)
Since each square meter costs $38.31, we would multiply the cost with the area,
Total Cost = 99 x 38.31
Total Cost = $3792.69

On a coordinate plane, an absolute value graph has a vertex at (negative 1, 0).
On a coordinate plane, an absolute value graph has a vertex at (0, negative 1).
Answers
The correct statement is: On a coordinate plane, an absolute value graph has a vertex at (0, 1).
The function p(x) = |x - 1| represents an absolute value function. The vertex of an absolute value function in the form f(x) = |x - h| + k is given by the point (h, k). In this case, the function p(x) = |x - 1| has a vertex at (1, 0).
Therefore, none of the provided options accurately represents the vertex of the function p(x) = |x - 1|. The correct vertex for this function is (1, 0), which means the vertex is at x = 1 and y = 0 on the coordinate plane. It is important to note that the vertex is located at (h, k) where h represents the x-coordinate and k represents the y-coordinate.

Standard Deviation for given set of data is 0.25634797778466.
What is standard deviation?
Standard deviation is a measurement of how evenly distributed a set of numbers is. Since the variance is the squared average of the squared deviations from the mean, it represents the square root of the variance.For instance: To determine the standard deviation, sum all of the numbers inside this data set, divide by the total number of numbers, and the result is the standard deviation.Given that,

Answer:
610.5
Step-by-step explanation:
First, we have to organize the data. We know that:
Mary the Manager slept for 999 hours,
Cam the Cashier slept for 333 hours,
Teddy the Truck Driver slept for 777 hours,
Sierra the Security Guard slept for 444 hours.
Next, we have to the the median number of hours of sleep.
To find the median:
First, we have to order the numbers from least to greatest. In this problem that is 333, 444, 777, 999. in an odd amount of numbers, like 5, the middle number is the median. In this case, however, there is not an odd amount of numbers, there are 4 numbers. Which means, we have to do the odd number equation:
We have to add the two middle numbers, which are 444, and 777 together, which results in 1,221. Finally, we must divide the result in half, which gives us out final total of 610.5

Answers
the sugar is sold at rupees 5.4 per kg at a loss of 10% at what price should it be sold per kg to earn a profit of 20%
Answer:
7.2 rupees
Step-by-step explanation:
Given that at a loss of 10 percent which is 90% price, we have sugar sold at 5.4 rupees per k.g
Hence, at 100 percent we have => 5.4 × (100 ÷ 90 )= 6 rupees per kg.
Therefore, at 100 percent, where we have 6 rupees per kg, to make a profit of 20% we have
6 rupees per kg x 120% = 6 × 1.2 = 7.2 rupees per kg.
Hence, the final answer is 7.2 rupees per kg to make a profit of 20%.

Determine whether or not the equations represent a direct variation. Sort the equation into appropriate category

Direct V:

Not direct V:
y=2.2x+7

Step-by-step explanation:
That was the answer on edge2020 :))
Direct variation usually conform to the general formula : \(y = kx \) where k is the proportionality constant. Hence sorting the equation into tbe appropriate category :
Direct variation :
y = 3x
Constant of proportionality, k = 3y = (2/7)x
Constant of proportionality, k = 2/7y = -0.5x
Constant of proportionality, k = -0.5Non - direct variation :
y = 2.2x + 7
Linear equation expressed in slope - intercept formy = 4 and x = - 1
These are variable declarations as the constants are only assigned to one variable and no unknown.Therefore, only three of the expressions exhibit direct variation while the other three do not.

How to subtract fractions with different denominators? Please explain step by step
Answers
Answer: 20/48
(simplified) 5/12
Step-by-step explanation:
We will use 6/8 - 2/6 for our example
6/8 - 2/6
Multiply the denominator on the right side by the denominator on the left side: 6x8 = 48
Make 48 the denominators on both sides: /48, /48
Now multiply the denominator on the left side with the numerator on the left side: 6x6 = 36
Make the first fraction's numerator 36: 36/48
Now multiply the denominator on the left side by the numerator on the right side: 8x2 = 16
Now make 16 the numerator of the second fraction: 16/48
Now that the denominators are the same, we can subtract!
36/48-16/48 = 20/48
Now to simplify:
divide 20/48 by 4 = 5/12
So the answer is 20/48 and when it is simplified it comes out to 5/12
This is how you subtract fractions with different denominators.
You can use the same method when adding, the only difference is that instead of adding in the last step, you add instead!

To estimate 179% of 41 by rounding, use the expression

Using the distributive property, the expression is equivalent to
.
179% of 41 is about
Answers
The estimate of 179% of 41 by rounding is about 73.19.
To find this estimate, first convert the percentage to a decimal by dividing it by 100: 179/100 = 1.79. Then, multiply this decimal by 41: 1.79 * 41 = 73.39.
Since we are rounding, we round this value to the nearest whole number, which is 73. Therefore, the direct answer is 179% of 41 is about 73.When estimating by rounding, we look at the decimal places. In this case, the hundredth place is 3. Since 3 is less than 5, we round down. Hence, the estimate is 73.19. It is important to note that rounding introduces some degree of error, as the actual value is 73.39. However, for most practical purposes, an estimate provides a close approximation that is quick and easy to calculate.For more similar questions on whole number
